Question

HELPPPpPpPPPpppP MEEEEEeeeEEE

Answer 1

This is a linear pair of angles so the sum of the degree measures equals 180 degrees.

Thus:

75 + x = 180

x = 180 - 75

x = 105 degrees

Answer 2

A straight line = 180 degrees, so the 2 angles shown need to also equal 180 degrees.

75 + x = 180

x = 180-75 = 105 degrees
